Description Grove - Adjustable PIR Motion Sensor is an easy to use Passive Infrared motion sensor, which can detect infrared object motion up to 3 meters. Any infrared object moves in its detecting range, the sensor outputs HIGH on its SIG pin. And you can adjust the SIG HIGH time up to 130s via the potentiometer, moreover, you can adjust the detect range via the other potentiometer. Feature Built-in filter, high immunity to RFI Output time, sensitivity and light control adjustable Low voltage, low power consumption Typical Applications PIR motion detection Intruder detection Occupancy detection Motion sensor lights Security system Automatic control,etc.
